i searched and couldnt find anything specifically explaining my issue so sorry if this has been covered. just finished swapping in a 6.0 in a new to me 99 2500 with hydroboost. engine now runs but my brake pedal is hard as a rock and i have no power steering. i have a steering cooler but all the lines to that and to the booster unit are not leaking. took off belt and the power steering pulley moves maybe 1/8" back and forth but not much at all. I have an abs light on. wondering if a failed brake booster would cause this issue? Thanks

 

Unhook the line to the booster, and see if it spins then. If it doesn't it's probably the pump.

 

bad power steering pump.

 

You should be able to spin the power steering pump pulley easily by hand, if you cant, you have a bad pump...

 

Did you have the lines off when you did the swap??? The ABS code might also be a good indication of whats going on... Do have a scan tool that can read ABS codes???
